Pre-insulated tubing bundles give field
advantages
The Swagelok Company introduces new electric and steam traced pre-insulated bundled tubing to expand their analytical and process instrumentation product line
The Swagelok Company introduces new electric and steam traced pre-insulated bundled tubing to expand their analytical and process instrumentation product line Swagelok traced bundled tubing is a predictable, repeatable, low-cost and easily maintained solution, which can be installed more quickly and can deliver more consistent thermal performance than field traced and insulated systems

The bundled tubing is used in a variety of instrumentation applications that require process fluid freeze protection, temperature maintenance, viscosity control and energy conservation, such as impulse, process and sampling lines.
An additional benefit of the Swagelok traced bundled tubing is that the individual tubes are installed parallel to each other, as apposed to cabled or twisted, which helps keep the tubing round, so fittings are easier to install and gives a tighter bend radius.
A variety of configurations with multiple process tubes and either electric or steam tracers are available.
The Swagelok tubing bundle is insulated with non-wicking, fibrous glass insulation and covered with a tough PVC or urethane jacket.
* Swagelok electric traced bundled tubing features a self-regulating electric tracer that lowers heat output as the bundle warms.
It is typically used to maintain process temperatures up to 250degF (121C), without the need for dedicated temperature controllers.
* Swagelok light steam traced bundled tubing provides freeze protection and maintains process temperatures between 50 and 200degF (10 to 93C).
The process tubes are separated from the tracer tubes by a layer of insulation that lowers the heat transfer rate and provides a more constant temperature over longer lengths of tubing.
* In Swagelok heavy steam traced bundled tubing, the process tube is in direct contact with the tracer to provide process temperature maintenance from 200 to 400F (93 to 204C).
